Description

[Detailed description of the invention] This invention relates to an electrode pad that is attached to each electrode surface of a so-called multi-electrode in which a large number of electrodes are implanted on a single substrate. (Peeling) can be performed accurately and easily.

Adhesive electrode pads made of conductive flexible material are temporarily attached to silicone release paper, and are normally separated and attached to the electrode surface during use, but as this pad itself is adhesive, it must be handled carefully. It was inconvenient.

This invention takes advantage of the fact that the first surface (priority release surface), which is obtained by cutting off or curving the outer peripheral corner of one side of the plate-shaped adhesive pad, and the second surface, which is a normal surface, have different releasability to the release paper. It is made by temporarily adhering both sides of an adhesive pad with a release surface between two sheets of silicone release paper.

To explain this using the diagram, 1 is a multi-electrode,
2 is a substrate, 3 is an electrode, 4 is a conducting wire, and 5 is a connection terminal.

Figure 2 is a plan view of the proposed product, showing the adhesive pad 6.
are arranged at intervals corresponding to the intervals of the multi-electrodes, and as shown in FIG. 3, a circular adhesive pad 6 is temporarily attached by being sandwiched between two pieces of silicone release paper 7, 8 in a sandwich pattern.

7a and 8a are silicone coated surfaces, respectively.

One surface of the pad 6 is cut off or provided with an R9 at its outer peripheral corner to serve as a preferential release surface 10.

In this product, when the two pieces of release paper 7 and 8 are opened from their ends in the direction of the arrow in FIG. I will remain wearing Patsudo 6 temporarily.

Place each pad on the release paper 8 on each electrode 3 as shown in Figure 4.
If the pads 6 are placed in the position and pressed lightly, each pad 6 will come into close contact with the surface of each electrode 3, so when the release paper 8 is pulled in this state, only the release paper 8 will be peeled off and removed due to the difference in adhesive strength, resulting in the result as shown in Figure 5. It can be used as is.

As described above, the present product is efficient and sanitary because when adhering the pad to the electrode surface, there is no need to touch the pad itself and the adhesion can be done accurately at a predetermined position.

Furthermore, when peeling off and removing each pad after use, each pad 6 can be easily separated from the electrode 3 by adhering the back side of ordinary paper 12 or release paper to the second surface of the pad and removing it, as shown in FIG. removed.

As mentioned above, this product is hygienic because it can handle the entire process from adhesion of the pads to detachment and removal without touching the pads themselves or the electrodes at all. It is extremely efficient because it can be done with one touch regardless of the situation.
